My first Infiniti was a j30 replaced all struts cost around $279/ea..sucks!!.. I've been reading the threads on replacement struts and kyb in particular. Seems the only difference is the stiffness! The fitment should not be an issue!!wingFeather wrote:Does anyone know what the difference is between base & Sport shocks (other than perhaps stiffness)??? I hope the mounting locations are all the same. I don't want another J30 where the front shocks are $500 a piece...
